THE IMPACT OF REARING DENSITY ON THE GROWTH AND SURVIVAL RATE OF SNUB - NOSE POMPANO AT THE STAGE OF FINGERLING.

Abstract

               The effect of rearing density on the growth and survival rate of snub - nose pompano in breeding stage. Results showed that the growth rate of the fish’s body weight was highest at the density of 1.5 ind./l and 2.0 ind./l, and lowest at the density of 4.0 ind./l and 4.5 ind./l. The coefficient of variation of the fish at the density of 1.0 ind./l, 1.5 ind./l and 2.5 ind./l was lower than that of the density of 4.0 ind./l. Food conversion ratio was lowest at the density of 2.5 ind./l, and highest at the densities of 1.0 ind./l and 3.0 ind./l. The survival rate of the fish reared at the density from 1.0 ind./l to 3.0 ind./l was higher than that of the density of 3.0-4.5 ind./l. From the results of this study, it is suggested that the most appropriate density for rearing snub - nose pompano in breeding stage was between 1.5 ind./l and 2.5 ind./l in order to optimize the rearing efficiency.
